The girls tweeted a snap of a poster advertising their new E! reality TV show Chasing The Saturdays and said: "What a day... at ma-hoosive conference introducing ourselves & #ChasingTheSaturdays @TheSaturdaysTV to American media!"

Rochelle's growing baby bump was clear to see at the launch, where she wore a navy, tight-fitting below-the-knee dress.

The girls have also revealed they will be performing their track What About Us on the Jay Leno show on January 14 - Frankie Sandford's birthday.
